BROODER 2 Sheets-Sheet 2 Filed Aug. 4. 1927 @vi/Immo Patented Oct. 15, 1929 WILBERT A. rAscoE, or sALT LAKE CITY, UTAH BROODER Application filed August 4, 1927. Serial No. 210,584.

rlhe invention aims to provide a new and improved brooder of rather simple and inexpensive construction, yet one which will be highly efficient and desirable, and will provide for effective heating as well as ventilation.

A further object of the invention is to provide a brooder which is readily adjustable to accommodate the chicks as they grow to a larger size from that at which they first occupied the broeder.

With the foregoing in view, the invention resides in the novel subject matter hereinafer described and claimed, the description being supplemented by the accompanying drawings.

Fig. 1 is a side elevation, partly broken away.

Fig. 2 is a vertical sectional view.

Fig. 3 is a perspective view of the base, the upper and lower sleeves which contain the heating means, and the radiator carried by the upper sleeve.

In the drawings above briefly described, the preferred form of construction has been illustrated, and while this construction will be herein specifically explained, it is to be understood that within the scope of the invention as claimed, variations may be made.

rlhe numeral 4 designates a base plate from whose central portion, a lower sleeve 5 rises, said sleeve and base plate being suitably joined to each other and being both preferably formed from galvanized sheet metal or other non-,corrosive material. At its lower end, the sleeve 5 is formed with air inlets 6 and at an elevation above these inlets, is provided with additional inlets 7, the latter being formed by inwardly stamping portions 8 of 4o the sleeve. These portions 8 decline inwardly from the upper ends of the openings 7 and they protect the chicks against glare from an electric bulb wh en the latter is used as a heating mea-ns for the brooder.

An upper sleeve 9 slidably surrounds the sleeve 5 and carries a hollow radiator 10 at its upper end. This radiator is in communication wtih the interior of the sleeve 9 and it preferably embodies a at bottom plate 11 se- V cured to said sleeve, and a concavo-convex top plate 12 whose peripheraledge is suitably joined to the peripheral edge of the bottom plate 11, the three parts 9, 11 and 12 being formed from galvanized or other non-cor rosive metal.

A conical hover 13 is provided, resting on the radiator 10, said hover being formed from suitable sheet metal and being preferably provided witha covering 1/1 of asbestos or other heat-insulating material. At its peripheral edge, this hover is provided with a` slitted curtain 15 which may be connected with it inv any desired manner. At its apex, thc hover is formed with an opening 16 which receives a stud or post 17, the latter being secured to and rising centrally from the top plate 12 of the radiator 10.

I/Vithin'the casing formed by the ,telescopic sleeves 5 9, I mount a heater. This heater is preferably in the form of an electric light bulbf18 whose socket 19 is suitably secured to the top plate 12` of the radiator 10.k The air entering the sleeves 5 9, is heated bythe bulb 18 and ascends into the radiator 10, from which some of it discharges through heat escape openings 2O in the bottom plate 11. As the discharged air cools, Vit settles within the space circuinscribed by the curtain 15, and some of this air re-enters the sleeve 5 through the openings 7 and 6, wherein it is reheated. In order to reach the openings 6 to enter the sleeve 5, the air must pass downwardly through-the usual litter 21, assisting in keeping the same dry. Moreover, in order for any outside air to reach the openings 6 or 7, it must flow inwardly from the slitted curtain 15, thus giving all chicks in thev brooder the .sam-e supply of fresh air. Obviously, some of the hot air from the interior of the device will escape through the curtain 1 5 and hence fresh air must enter to take its place, providing effective ventilation.

- rWhen the `brooder is to be used for small chicks, the hover 13 and curtain 15 must be much lower than when the chicks grow to larger size. To permit raising and lowering of such hover and the radiator 10, the sleeve 9 is slidable upon the lower sleeve 5 and it may be held in vertically adjusted position by any desired means, suchas a screw 22. f While the chicks are very small, this screw may be passed through an opening 23 in the sleeve 5 and the sleeve 9 then rests upon it as shown in Fig. 2. l/Vh-en the chicks grow to larger size however, the sleeve 9 may be slid upwardly and the screw 22 placed in a higher opening 28a. Upon making this adjustment, it will be seen that the radiator 10, bulb 18 and hover 13 are all raised, so that the device will more readily accommodate the larger chicks and they will not be supplied with an excessive heat. Too much direct radiation of heat from the sleeves 5-9 is prevented, in either adjustment of the brooder, by a suitable lining sleeve 24twhich is secured in the sleeve 5 and spaced therefrom,providing a dead air insulating space 25.

Excellent Vresults are obtainable from the details disclosed and they may therefore be followed as above stated. However, within the scope of the invention as claimed, varia-- tions may be made.

I claim l. A brooder comprising a fiat base plate,

a sleeve secured to and rising from said base,

an upper sleeve slidably telescoped with the irstsnamed sleevev and providing therewith a heater casing, said first named sleeve having air inlet means into said casing, a hollow radiator having a bottomY plate secured to said upper sleeve and communicating with the interior thereof, a hover supported by said radiator, and means for normally holding the aforesaid sleeves against relative sliding.

2. A brooder comprising a flat base plate, a lower sleeve secured to and rising rigidly from said base, said sleeve having air inlet means, an upper sleeve slidably telescoped with said lower sleeve, means for normally supporting said upper sleeve against downward sliding on the lower sleeve, a hollow radiator having a Hat bottom plate secured to the upper' end of said upper sleeve and communicating with the interior of the latter, a hover supported by said radiator, and an electric heater within said sleeves, said heater' having a socket secured to the upper portion of said radiator.

3. A brooder comprising a base, a heater threaded stud rigidly secured in the center of the top plate of said radiator and projecting o a considerable distance above saidtop plate and a conical hover resting on said radiator and having a small opening inl its apex through which said stud passes and closely lits thereby holding said hover centered on said radiator. Y

4.' A brooder comprising av base, a lower sleeve securedto and rising rigidly from said base, saidv sleeve. having air inlet means, an

upper sleeve slidably telescoped withY said lower sleeve, means for normally supporting said upper sleeve against downward sliding on the lower sleeve, a hollow vradiator comprising a flatl bot-tom plate and a'concavoconvexrtop plate joined at their peripheral edges, said bottom plate having a series of hot air discharge openings and a central opening the edges of which are integrally joined with the upper edge of said upper sleeve, whereby said radiator and sleeve are in communication, means for adjustably support-ing said upper sleeve against downward sliding movement on said lower sleeve, a hover supported by said radiator and an electric heater secured to the upper plateofsaid radiator andenT tending downwardly through the Aradiator and into said sleeves.

ln testimony whereof I have hereunto affixed my signature.
